5 config SCSI_AIC7XXX
6 tristate "Adaptec AIC7xxx Fast -> U160 support (New Driver)"
7 depends on (PCI || EISA) && SCSI
8 select SCSI_SPI_ATTRS
9 ---help---
10 This driver supports all of Adaptec's Fast through Ultra 160 PCI
11 based SCSI controllers as well as the aic7770 based EISA and VLB
12 SCSI controllers (the 274x and 284x series). For AAA and ARO based
13 configurations, only SCSI functionality is provided.
1415 To compile this driver as a module, choose M here: the
16 module will be called aic7xxx.
1718 config AIC7XXX_CMDS_PER_DEVICE
19 int "Maximum number of TCQ commands per device"
20 depends on SCSI_AIC7XXX
21 default "32"
22 ---help---
23 Specify the number of commands you would like to allocate per SCSI
24 device when Tagged Command Queueing (TCQ) is enabled on that device.
2526 This is an upper bound value for the number of tagged transactions
27 to be used for any device. The aic7xxx driver will automatically
28 vary this number based on device behavior. For devices with a
29 fixed maximum, the driver will eventually lock to this maximum
30 and display a console message indicating this value.
3132 Due to resource allocation issues in the Linux SCSI mid-layer, using
33 a high number of commands per device may result in memory allocation
34 failures when many devices are attached to the system. For this reason,
35 the default is set to 32. Higher values may result in higher performance
36 on some devices. The upper bound is 253. 0 disables tagged queueing.
3738 Per device tag depth can be controlled via the kernel command line
39 "tag_info" option. See Documentation/scsi/aic7xxx.txt for details.
4041 config AIC7XXX_RESET_DELAY_MS
42 int "Initial bus reset delay in milli-seconds"
43 depends on SCSI_AIC7XXX
44 default "5000"
45 ---help---
46 The number of milliseconds to delay after an initial bus reset.
47 The bus settle delay following all error recovery actions is
48 dictated by the SCSI layer and is not affected by this value.
4950 Default: 5000 (5 seconds)
5152 config AIC7XXX_BUILD_FIRMWARE
53 bool "Build Adapter Firmware with Kernel Build"
54 depends on SCSI_AIC7XXX && !PREVENT_FIRMWARE_BUILD
55 help
56 This option should only be enabled if you are modifying the firmware
57 source to the aic7xxx driver and wish to have the generated firmware
58 include files updated during a normal kernel build. The assembler
59 for the firmware requires lex and yacc or their equivalents, as well
60 as the db v1 library. You may have to install additional packages
61 or modify the assembler Makefile or the files it includes if your
62 build environment is different than that of the author.
6364 config AIC7XXX_DEBUG_ENABLE
65 bool "Compile in Debugging Code"
66 depends on SCSI_AIC7XXX
67 default y
68 help
69 Compile in aic7xxx debugging code that can be useful in diagnosing
70 driver errors.
7172 config AIC7XXX_DEBUG_MASK
73 int "Debug code enable mask (2047 for all debugging)"
74 depends on SCSI_AIC7XXX
75 default "0"
76 help
77 Bit mask of debug options that is only valid if the
78 CONFIG_AIC7XXX_DEBUG_ENABLE option is enabled. The bits in this mask
79 are defined in the drivers/scsi/aic7xxx/aic7xxx.h - search for the
80 variable ahc_debug in that file to find them.
8182 config AIC7XXX_REG_PRETTY_PRINT
83 bool "Decode registers during diagnostics"
84 depends on SCSI_AIC7XXX
85 default y
86 help
87 Compile in register value tables for the output of expanded register
88 contents in diagnostics. This make it much easier to understand debug
89 output without having to refer to a data book and/or the aic7xxx.reg
90 file.
